Abstract content Silicon Photomultipliers (SiPMs) are a promising candidate for replacing conventional photomultiplier tubes in many applications, thanks to ongoing developments and advances in their technology. A drawback of conventional SiPMs is their limited fill factor caused by the need for a high ohmic polysilicon quench resistor and its metal lines on the surface of the devices, which in turn limits the maximum photon detection efficiency. At the Semiconductor Laboratory of the Max-Planck Society (HLL) a novel detector concept was developed integrating the quench resistor directly into the silicon bulk of the device resulting in a free entrance window on the surface. The feasibility of the concept was already confirmed by simulation and extensive studies of first prototype productions. Recently SiPMs were also considered as an attractive alternative for tracking applications in vertex detectors. The requirements for a fast response, simple design and high fill factor can all be met by SiPMs. In addition the increased trigger probability for an avalanche by minimum ionizing particles allows device operations at lower overbias voltages, resulting in a decreased noise contribution. The concept can be evolved further towards an imaging photo-detector. A new design for an application of these SiPM devices as vertex detectors with active quenching developed by the HLL and DESY as well as first simulation results will be presented. Also, first measurements of the trigger efficiency as a function of the applied overbias voltage of SiPM devices will be shown.

The Geiger-mode operation of a SiPM requires a high-ohmic quench resistor, which is usually realized in conventional devices by a structured polysilicon layer on the surface, leading to a decrease of the maximum photon detection efficiency (PDE). In order to improve on this drawback, the Semiconductor Laboratory (HLL) of the Max-Planck-Society has developed a novel detector concept with the quench resistor integrated into a high-ohmic silicon bulk. This in turn results in a free and unstructured entrance window for photons on the surface of the device. In a first prototype production the proof of concept of this novel approach was confirmed and additional prototypes for devices improvements were developed. A brief general overview of our novel SiPM approach as well as its advantages and disadvantages will be discussed. In addition, the latest results of the characterization of SiMPl devices, including the PDE, optical cross talk and recovery time as well as an outlook for further improvements in the device performance will be presented.

The tracker system will have a major overhaul. Its components will be replaced with new technologies in order to cope with the increased hit occupancy and radiation environment. A detector made of scintillating fibres read out by silicon photomultipliers (SiPM) is studied for this upgrade. Even if this technology has proven to achieve high efficiency and spatial resolution, its integration within a LHC experiment bears new challenges. This detector will consist of 12 planes of 5 to 6 layers of 250um fibres with an area of 5x6m2. Its lead to a total of 500k SiPM channels which need to will be read out at 40MHz. This talk gives an overview of the R&D status of the readout board and the PACIFIC chip. The readout board is connected to the SiPM on one side and to the experiment data-acquisition, experimental control system and services on the otherside . The PACIFIC chip is a 128 channel ASIC which can be connected to one 128-channel SiPM without the need for any external component. It includes the analog signal processing and a 2 bits non-linear flash ADC for digitisation. The PACIFIC chip design highlights a very fast shaping (~10ns) and the ability to cope with different SiPM suppliers with a power consumption below 8mW per channel.

To ensure high tracking performance over the entire experiment's lifetime, the SiPMs will be operated at sub-zero temperatures, down to -40ºC. This presentation outlines the proposed SiPM cooling system and describes the design considerations which led to the choice of the mono-phase liquid cooling solution. The requirements on the temperature uniformity and stability are discussed, along with the constraints which thermal considerations impose on the mechanical design of the tracker modules. The prospective refrigerants (C6F14 and 3M Novec thermal fluids) are compared with each other, including their effect on the environment. The SiPM cooling system consists of the remote cooling plant, insulated transfer lines, the local distribution pipework and the cooling structures inside 288 read-out boxes spread over twelve 5x6 m2 tracker planes. The main design challenges of this system are associated with its large extent (about 150 m of linear SiPM arrays to be cooled) and severe constraints on the geometrical envelope and, hense, insulation. Since the SiPM themselves produce very little heat, the estimated heat load of the cooling plant, 13 kW, is dominated by the heat influx through the insulation of read-out boxes, interconnection and transfer lines. Main system design parameters, as well as the latest results of the thermal mock-up tests, are summarised.

The readout electronics for such systems must guarantee stable operation during the whole data taking phase. Major experiments in the field are CUORE and LUCIFER, both based on macrobolometers and currently under construction underground at the Laboratori Nazionali del Gran Sasso (LNGS) in central Italy. The electronic readout system for these experiments is being designed and built to meet the required stringent specifications on low noise and stability. The power supply system must provide the front-end electronics with very stable operating voltages, and is composed by three items. Commercial AC/DC converters are used to provide a +48 V supply from the mains line. Several low ripple DC/DC converters are used to bring the +48 V to dual ±8 V, ±12 V and ±15 V to the crates housing the electronics. The last and most critical stage is composed by linear power conditioners with low noise (< 0.1ppm, down to 0.1 Hz) and low drift (a few ppm/°C) to provide the detectors and the front-end electronics with the required operating voltages. The output voltages can be set between +/- 3.75 V and +/- 12.5 V in eight steps. The rated current from each output is 4 A. The circuits are protected against failures and shorts at the output by a novel thermal foldback scheme, that dinamically adjusts the maximum output current based on the temperature the output transistor.

Two SiPM manufacturers, Hamamatsu and KETEK have developed customized devices for SciFi Tracker application in the context of the LHCb tracker upgrade. These custom devices provide high photon detection efficiency (PDE) in a large wavelength range, high reliability due to its simple mechanical construction, a high density multi-channel package and are of sufficiently low cost to build a large area tracking device. There are several challenging requirements placed on the photo-detector mainly due to the neutron radiation environment and the low light output of the long scintillating fibre modules. New devices with the latest technological improvements implemented are available in spring 2014. This includes devices with different optical isolation between pixels (trenches) and different pixel sizes. The dark noise rate (DCR) increases strongly with irradiation and the noise cluster rate of the tracking device can only be kept sufficiently low at a temperature of -40°C. We present the results on PDE, cross-talk and noise before and after neutron irradiation at various temperatures. The results are compared for the latest and the devices based on the standard technology.

The large particle density in the forward region poses extreme challenges to the subdetectors, in terms of hit occupancies and radiation tolerance. To accurately and efficiently detect the charged decay particles in the high-density particle environment of the LHC the Outer Tracker (OT) has been constructed. The OT is a gaseous straw tube detector, consisting of 53,760 straw tubes, covering an area of 360 m2 of double layers. At the time of the conference, the performance of the OT during run I of the LHC has been scrutinized. The detector has operated under nominal LHC conditions for a period of over 2 years, corresponding to an integrated luminosity of approximately 3 fb-1. A remarkable radiation resistance of this sensitive gas detector is reported. Unlike most other subdetectors in LHCb, constructed with various technologies, no sign of ageing is observed after having received a total dose corresponding to about 100 mC/cm in the hottest region. Two independent and complementary methods have been used to measure the radiation resistance of this gas detector in the forward region at the LHC. One method uses a dedicated setup in situ, with which a 90Sr source is scanned over the surface of part of the OT detector. The second method utilizes reconstructed tracks duing LHC operation, with which the hit efficiency over the full detector surface is determined at increased amplifier threshold.

Dark Matter Experiments based on liquid xenon have set the most stringent limits in the past decade and are still leading the field. Also in other areas of particle physics xenon is used as detector medium, for example in the search for neutrinoless double beta decay (EXO), in the search for lepton flavor violation (MEG) or in envisioned projects like gamma ray telescopes on satellites. There is also ongoing research on xenon-based detectors for medical imaging. Although widely used, the scintillation process of liquid xenon, especially at low recoil energies (few keV), is not well understood. The MainzTPC, a small 3D position-sensitive dual-phase xenon TPC, has the goal to improve our understanding of the scintillation process and the field quenching in liquid xenon. The MainzTPC uses two PMTs (Hamamatsu R6041) to detect and measure the fast primary scintillation light including its shape. Additionally an array of eight large area avalanche photo diodes (LA-APDs) detects the large proportional scintillation providing x/y resolution. Here we report on the performance of the TPC and the response of the LA-APDs to the xenon scintillation light. Summary The design of the MainzTPC and the according cryo-system is finished and its assembly is ongoing at the moment. Till the TIPP2014 we expect to have the TPC running and first tests performed. Meanwhile the photosensors that will be used are tested and characterized. The Large Area APDs are tested in liquid xenon on quantum efficiency for the xenon scintillation light as well as the voltage and temperature dependence of their internal gain (g>1000). Also, the DAQ using a high sample rate (5GS/s) FADC is setup in parallel to the measurements of the light detectors and construction and assembly of the TPC. In the talk, we will report on the response of the photo sensors (especially the APDs) and the comissioning and first results from the comissioning of the TPC.

The telescope consists of six monolithic active pixel sensor planes (Mimosa26) with a pixel pitch of 18.4 \mu m and thinned down to 50 \mu m. The excellent resolution, readout rate and DAQ integration capabilities made the telescope a primary test beam tool for many groups including several CERN based experiments. Within the European detector infrastructure project AIDA the test beam telescope is being further extended in terms of cooling and powering infrastructure, read-out speed, area of acceptance, and precision. In order to provide a system optimized for the different requirements by the user community a combination of various state-of-the-art pixel technologies is foreseen. Furthermore, new central dead-time-free trigger logic unit (TLU) has been developed to provide LHC-speed response with one-trigger-per-particle operating mode and a synchronous clock for all connected devices. In this report, the design and current development status of this even more flexible telescope with three different pixel technologies (TimePix, Mimosa, ATLAS FE-I4) will be presented.

The first prototype was designed and fabricated in CMOS 130 nm technology. The main chip components are 8 channels of fast, very low power (<0.5 mW per channel) 6-bit SAR ADCs, data serialization circuitry based on ultra-low power internal PLL and fast SLVS I/O differential interface. The nominal ADC sampling frequency is 40 MHz but the operation beyond 80 MHz is possible. Various modes of data serialization were implemented, the main three are: A) test mode - with 6 bits from the selected ADC sent to 6 SLVS differential outputs; B) partial serialization - when output bits of each ADC are serialized, with frequency multiplied six times by PLL, into separate SLVS output; C) full serialization - when output of all (6) bits of all (8) ADCs are serialized into one SLVS output. In addition to standard operation the serialization circuitry contains also a block generating the test data (instead of using ADC output bits) which are serialized and sent out. This block is added for better ASIC testability and it allows to generate test patterns based on binary or pseudo-random counters. The ultra-low power (<1 mW) PLL was designed to generate clock in a wide frequency range, from tens of MHz to few GHz. The SLVS interface was designed for data rates beyond 1 GHz. The description of the ASIC architecture and the results of measurements, in particular all main functionalities/blocks i.e. ADC, PLL, SLVS and serializer will be presented.
